Lab #2: Using ArcMap—projection and cartographic visualization

Question 1: List the buttons in the Data Frame Properties Coordinate System window. Give a short description of the function of each button.

Clear- Removes the coordinate system from the data frame

Transformations- Defines changes in the coordinate system

Modify- Edits the parameters of the coordinate system

Import- Lets you browse for a coordinate system

New- Lets you create a new coordinate system

Add To Favorites- Adds the coordinate system to a list of favorite systems

Remove From Favorites- Removes the coordinate system from the list of favorites

Question 2: Has the shape and appearance of the United States changed? If so, how?

The shape became more curved and the size is slightly smaller.

Question 3: List the names and values of the parameters that appear in the Coordinate System tab in Data Frame Properties window for this coordinate system.

USA_Contiguous_Albers_Equal_Area_Conic

Projection: Albers

False_Easting: 0.000000

False_Northing: 0.000000

Central_Meridian: -96.000000

Standard_Parallel_1: 29.500000

Standard_Parallel_2: 45.500000

Latitude_Of_Origin: 37.500000

Linear Unit: Meter

Question 4: Given the appearance of the data now, do you feel that the Albers Equal Area Projection is appropriate for viewing the entire world? Attach and describe the current view.

This projection is not appropriate for viewing the entire world because the shapes of some of the countries are very distorted.

Question 5: Describe and attach the current ArcMap window.

The window shows a page with four identical projections.

Question 6: Describe the difference between the four Data Frames: three projected and one unprojected.

The main difference is the shape of the projection. The Robinson and Sinusoidal ones have different shapes, while the Mercator and the GCS North American 1983 are both rectangular. In the Mercator map, however, the areas near the poles are larger than those in the GCS map.

Question 7: Choose one layout out of four layouts to make your final map. Put your final map including text, legend, north arrow, scale bar, etc. on your lab report.
